Amyotrophic lateral sclerosis (ALS) is a devastating and universally fatal neurodegenerative disease. Mutations in two related RNA-binding proteins, TDP-43 and FUS, that harbor prion-like domains, cause some forms of ALS. There are at least 213 human proteins harboring RNA recognition motifs, including FUS and TDP-43, raising the possibility that additional(More)
Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease affecting motor neurons. Mutations in related RNA-binding proteins TDP-43, FUS/TLS and TAF15 have been connected to ALS. These three proteins share several features, including the presence of a bioinformatics-predicted prion domain, aggregation-prone nature in vitro and in vivo and(More)
Regulation of gene expression by small RNAs ( approximately 20-30 nucleotides in length) plays an essential role in developmental pathways and defense responses against genomic parasites in eukaryotes. MicroRNAs (miRNAs) and small interfering RNAs (siRNAs) commonly direct the inactivation of cognate sequences through a variety of mechanisms, including RNA(More)
Double-stranded RNA, processed to small interfering RNAs (siRNAs) by Dicer and incorporated into the RNA-induced silencing complex (RISC), triggers gene silencing by a variety of pathways in eukaryotes. RNA interference involving the degradation of homologous transcripts is the best-characterized mechanism. However, the fate of the RNA fragments resulting(More)
Motor neuron diseases (MNDs) are neurodegenerative disorders that lead to paralysis and typically carry a dismal prognosis. In children, inherited spinal muscular atrophies are the predominant diseases that affect motor neurons, whereas in adults, amyotrophic lateral sclerosis, which is inherited but mostly sporadic, is the most common MND. In recent years,(More)
RNA binding proteins (RBPs) have emerged as major causative agents of amyotrophic lateral sclerosis (ALS). To investigate the function of TAF15, an RBP recently implicated in ALS, we explored its target RNA repertoire in normal human brain and mouse neurons. Coupling high-throughput sequencing of immunoprecipitated and crosslinked RNA with RNA sequencing(More)
